The invention relates to improvements in filters such as disclosed in myprior Patent, No. 931,267, dated August 17, 1909, and has for itsprimary object the provision oi improved means for effecting dischargeof the contents of: the filter chamber.

Another object of the invention is the provision of an arrangement ofthis character by means of which the discharge of the chamher may bequickly and conveniently effected.

Another object of the invention is the provision of an arrangement ofthis character entirely mounted on and contained in the filter chamber.

. Other objects'will appear hereinafter.

The invention consists in the combinations and arrangement of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification and in which Fig. 1 is apartial vertical section taken through the discharge end of the filterchamber and showing discharging means embodying the invention;

Fig. 2, a detail view showing a connecting collar employed in theconstruction; and

Fig. 3, a section taken substantially on the line 33 of Fig. 1.

The preferred form of construction, as illustrated in the drawings,comprises a suitable revolving filter chamber lhaving a removabledisch'arge end 5 bolted thereto as indicated. The discharge end 5 isprovided with a plurality of discharge openings arranged immediatelyadjacent to interna periphery of the chamber 4. Each of said openings isguarded and protected by means of a nipple 6, which may be of specialnoncorrosive metal, secured in place as shown. At is inner end, eachnipple 6 is provided with a conical valve surface, effecting a ti rrhtseal with the inner portion of the opening and also projecting into theinterior of the chamber to constitute a valve or closure seat Each ofsaid openings is closed by means I. of a valve or closure head 8 rigidlysecured to the lnner end of an operating stem 9 proectmg through thecorresponding opening and rigidlysecured at its outer end to acorresponding lever 10. The levers 10 are arranged in radiatingpositions, being fulcrumed at 11 between suitable cars 12' formed on theouter side of the. chamber end 5. At its inner end, each of the .levers10 is provided With aslot 13 engaging a corresponding pin 1-; betweenparallel cars 15 on the inner face of a collar- 16. The collar 16 issplit, as indicated, into two halves secured together by bolts 17 and isprovided with an internal annular groove engaging an annular flange 18on the inner end of a nut sleeve 19. The not sleeve 19 is threaded on acentral post 20 and provided With a hand wheel 21 for manipulation ofthe same. At its outer end, the post 20 is provided With a stop collar22 held in place by a nut 23 and is enclosed andv protected by aguardcap 24.

By this arrangement, the valves or closure heads 8 may besimultaneouslyoperated by manipulating the hand WheelQl to open or close the dischargeopenings through the chamber end 5, as will be readily understood. Thisconstitutes a simple and ,eiiicient arrangement for the purpose, mountedentirely upon the filter chamber and requiring no additional support ormechanism.

A relief Valve 25 is also provided on the end 5 to permit of relief ofinternal pres sure in the filter chamber, thus facilitating opening ofthe valves 8. A suitable manhole and cover 26 is also provided forgiving access to the interior of the filter chamber.

' While the preferred form of construe tion for carrying the inventioninto effect has been illustrated and described, this is capable or"variation and modification without departing from the spirit of theinvention. lit is, therefore, not desired to limit the patcut to theprecise details disclosed but to include therein also such variationsand modifications as fall within the scope of the appended claims.

I claim: 1. In a filter of the type specified, the combination of ahollow casing, means for rotatably mounting said casing, a fixed headfor closing the discharge end of said casing provided with a dischargeopening, a closure for said opening, and means mounted on the dischargeend of the filter casing for supporting and operating said closure toclose, open and position the same, said means forming a constituent partof the filter.

2. A filter as specified in claim 1, in which the closure for thedischarge opening opens inwardly.

3. In a filter of the type specified, the combination of a hollowcasing, means for rotatably mounting said casing, a fixed head forclosing the discharge end of said casing provided with a plurality ofspaced discharge openings, arranged adjacent its periphery, anindividual closure for each discharge opening, and means mounted on thedischarge end of the filter casing for supporting and operating saidclosures to simultaneously close, open and position the same,respectively.

i. A filter as specified in claim 1, which comprises a lever pivotallymounted on the discharge end of the filter casing to which the closureis secured, a threaded post secured in the discharge end of said filtercasing, a nut having threaded engagement with said post, and operativeconnection between said nut and lever.

5. A filter as specified in claim 1, which comprises alever mounted onthe discharge end of the filter casing, a stem rigidly secured thereto,which extends through the discharge opening into said filter casing, tothe outer end of which said closure is rigidly secured, a threaded postsecured in the end of said filter casing, a nut having threadedengagement with said pos and operative connection between said nut andlever.

6. A filter as specified in claim 8, which comprises a plurality oflevers pivotally mounted on the discharge end of the filter casing, astem rigidly secured in each of said levers, to the outer ends of which,respectively, one of said closures is rigidly secured, a threaded postsecured in the end or" said filter casing, a nut having threaded engagementwith said post, and operative connection between said nut andlevers.

7. A filter as specified in claim 3, which comprises a plurality oflevers pivotally mounted on the end of said filter casing, outsidethereof, a stem rigidly secured in each of said levers which extendsthrough a discharge opening into said receptacle, to the outer end ofwhich the closure for the opening through which said stems extend,respectively, is secured, a threaded post secured in the end of saidreceptacle, a nut which has threaded engagement with said post, andoperative connection between said nut and levers.

In witness that I claim the fcregoing as my invention, 1 ailix mysignature this 30 day of November, 1928.
